Re: hp photosmart c309a: USB Device not compatible: Remove USB device

I would suggest downloading and running the HP Printing Diagnostic Utility. If this does not resolve the issue try resetting the printer - with the printer turned on unplug the USB cable from the back then disconnect the power for 60 seconds. Plug the power back in and say OK when the printer says not to do that again, then reconnect the USB cable if you are connected by USB.

If that does not fix the problem then please read this post then provide some details. What operating system? How is the printer connected - USB, wired LAN, Wireless LAN, bluetooth? Are there any devices plugged into the card slots or USB port on the front left of the printer?

I've basically given up and physically reconnected the printer to my laptop. Solved most of my problems...

After spending multiple hours on the phone with HP tech support, with no resolution, then to be told "I have to run to the "lab" to test some issues, I will call you back in less than an hour". That was three months ago. Each time I called tech support, it was a long, arduous journey. Never want to do that again. Ever. If my time was money, I could have bought a new printer for each time I had to deal with tech support.

Bottom line, I bought a wireless printer so I didn't have to constrain myself to the desk while printing, and I could use it with the other laptops I and my business own. (They can no longer use the printer either) The frustrations I have experienced with this model and tech support (aside from the folks that have tried to help on this forum) have led me to the conclusion that I will not be purchasing HP in the future. And I will tell all those who will listen.

At the very least, my headaches will be caused by another company in the future.

The printer requires a master reset. To accomplish this, remove the power cord and then hold down both the '#' and "6" keys on the printer's panel while you plug back in the power cord. Release the '#' and "6" keys when the reset message appears and then follow instructions on the panel to finish the reset which will take several minutes to complete.
